Ranchers switch cattle to "healthy whole grains" before market for one reason: it fattens them up. Take a look at what's on your plate.

At 27, I was training 12+ hours a week and still overweight. My elbows hurt so badly I thought I'd have to quit climbing. Then I found out half of what I'd been taught about eating was backward.

Once I fixed it, I dropped 20 pounds in 4 weeks and the elbow pain went away. Now I'm 47. I train about twice a week, I don't count calories, and staying lean is the easiest part of my life. (Current project: 10 one-arm pull-ups in a row.)

This 17-page guide is the system I use: 30,000+ hours of studying biochemistry, boiled down to what actually moves the needle.

Inside:

• Why "calories in, calories out" falls apart, and what insulin is really doing to your fat stores

• The exact foods I cut, and what I eat instead, without feeling starved

• How I eat to fuel hard training and stay lean all year

• The training style that burned more fat for me than cardio ever did

• How to eat for health and performance for life, not a 6-week crash diet

This isn't a diet you suffer through and quit. Eat the way humans evolved to eat, and staying lean takes care of itself.

I'm not a doctor. Check with one you trust before changing your diet or training. This isn't personal medical advice.
